Roof leaks

What are you supposed to do when your roof is leaking every time it rains and it seems impossible to get a roofer who is actually available to do the work?

I've had one roofer look at it and say it is the lead flashings that are not completely meeting the tiles and so the leak is from that gap. But they are now busy and can't book the job in for ages. Meanwhile the plaster in the ceiling is getting damaged more and more and I'm worried it will reach the light fitting or that a part of the ceiling will collapse. And who knows what is going on in the loft space with the timbers and insulation.

Is there such a thing as a reliable emergency roofer who could actually fix it this week, not in 2 months time?! Feeling completely frustrated about this.

Where in the country are you? We managed to get someone out last minute from Checkatrade in a similar situation after lots of ringing around. We had a ceiling collapse in our first house so I never leave roofing issues anymore.
